As someone who has been a professional 'big' computer designer for over 35 years and am now working on the new 'post electronic' computers ...

Do you give out autographed photos with the highlights of your CV on the back?

LOL! No, that would be far too subtle.

... you could do this with an Arduino and an H-bridge motor driver board.

That was difficult .

(The £3 L298 module arrived yesterday. The telemetry link back to the DX9 is effectively being used to give the Arduino a display.)

The above solution is a bit overkill, but a fun experiment. Phil had the right idea and if the motor stall is a problem, as high current drain etc, then just fit a resettable fuse. They cost next to nothing.

Cheer, Nik

The Orangutan and Baby Orangutan boards from Pololu combine a 328P and a bridge in one neat board.

The TB6612FNG chip looks interesting and is available on a board for very little money.
